ActiveBasic multiplexing structure for synchronous digital hierarchy signals
同步数字体系信号的基本复用结构
Application Summary AI generated
This standard defines the multiplexing structure for Synchronous Digital Hierarchy (SDH) signals, specifying how lower-rate tributary signals are mapped and combined into higher-rate SDH frames. It is applied in the design, testing, and operation of optical transport networks and telecommunications equipment to ensure interoperability between different vendors' SDH systems. The standard is essential for network engineers and procurement professionals working on backbone transmission networks, metro networks, and access networks that rely on SDH technology.
